A stenotic aortic valve
A)causes right ventricular hypertrophy and right-sided heart failure.
B)increases afterload,thereby increasing the work of the left ventricle.
C)causes a right-to-left shunt.
D)is a narrowing of the right semilunar valve.

Question

Quizplus · Accepted Answer

A stenotic aortic valve narrows the opening through which blood leaves the left ventricle and enters the aorta, leading to increased resistance to blood flow and increased afterload. This increase in afterload causes the left ventricle to work harder to pump blood out of the heart and can eventually lead to left ventricular hypertrophy. It does not cause right ventricular hypertrophy or right-sided heart failure, nor does it cause a right-to-left shunt. Additionally, the aortic valve is a semilunar valve on the left side of the heart, not the right.
